Den Transport von Wärme mit nanostrukturierten Materialien präzise steuern zu können, ist das derzeit noch weit entfernte Ziel eines Forschungsgebiets, auf dem - trotz vielversprechender Anwendungspotenziale - weltweit nur wenige Wissenschaftlerinnen und Wissenschaftler arbeiten. Einer von ihnen ist Prof. Dr. Markus Retsch, seit 2012 Juniorprofessor für Polymere Systeme an der Universität Bayreuth. Die VolkswagenStiftung hat jetzt die Fördermittel bewilligt, damit er hier in den nächsten fünf Jahren eine Lichtenberg-Professur übernehmen kann. Damit sind an der Universität Bayreuth bald drei Lichtenberg-Professuren auf zukunftsweisenden Gebieten der Physik und der Chemie angesiedelt.
